Abstract:

Urban rail transit consumes a lot of energy, which is not only an important source of carbon emissions, but also a key field to promote the development of green energy and achieve the dual carbon strategic goals. Urban rail transit energy storage technology can not only absorb regenerative braking energy on a large scale, improve the energy utilization rate of trains, but also promote the nearby absorption of renewable energy and expand rail transit energy supply. It is an effective way to achieve the strategic goals of “green and low-carbon” sustainable development such as energy saving, emission reduction and effective use of clean energy in rail transit. The renewable energy applications in the field of rail transit and significance are analyzed, and the inverter feedback type and energy storage type regenerative braking energy recovery technology and application examples are introduced in depth. The performance characteristics of various energy storage technologies and their applications in the field of rail transit are summarized. Energy storage technology with high energy density, high power density and long life is the core of application in this field. A basic architecture of transit and energy connectivity based on energy storage technology is proposed, two energy scheduling modes of “rail transit-energy storage system-electric vehicle” and “rail transit-energy storage system-renewable energy” are analyzed through “source-network-load-storage” collaborative planning.

Key words: Energy storage technology, urban rail transit, green and low-carbon, regenerative braking energy recovery
